Methodology How the numbers are calculated, and where they come from

How taxwizard.pk calculates your tax.

Every rate on this site is cited against the Finance Act 2026 and the Income Tax Ordinance 2001. This page lists the exact clauses, shows which table applies to which year, and lets you check the arithmetic yourself.

Where the rates come from

Salaried income is taxed under the First Schedule, Part I, Division I, clause (2) of the Income Tax Ordinance 2001. Individuals other than salaried, and Associations of Persons (AOPs), are taxed under clause (1) of the same Division.

The surcharge is levied under section 4AB of the Ordinance: 10% of the computed income tax where taxable income exceeds Rs 1,00,00,000. Salaried individuals paid this surcharge at 9% in FY 2025-26; the Finance Act 2026 abolished it for the salaried class from FY 2026-27 onward, while it remains in force for non-salaried and AOP filers.
